I have a query. In most cases everyone says C 1s correction is done to avoid charging effect in all samples. But in my case for Sr5(PO4)3OH material and doped with cobalt, I have carbon 1s peaks at around 279 eV and at 284.6 eV. So I am getting confused, what does this 279 eV actually represent. Is this consistent with my data or something is wrong, like what does this peak of Carbon 1s represent?
Hello Anshul
The second peak at "279" is not Carbon but the Sr 3p1/2 as your material contains Sr ;-). If you enlarge the spectral range you'll see the corresponding Sr 3p3/2 with twice the intensity at ~269eV
Ciao Karsten
Karsten Fleischer Thank you sir For your help. Id did some digin and found the same answer as mentioned by you. But I wanted to know sir, I have the high resolution data of C 1S, can we have data or peaks of different elements too. And for 2P3/2 at 269 eV, the data I have, carries that much only on the graph I posted, so I don't have that information.
Be careful about the C1s correction, it may lead to incorrect values. See
